Many of the things that we face every day, have their own definition of interest.
Personally, I've never heard of this.
Akersekomik (Acersecomic) - people who have never had a haircut
Biblioklasm (Biblioclasm) - Ceremony of burning books and scientific papers, often solemn.
Cacodemonomania (Cacodemonomania) - pathological belief that man lives in an evil spirit
Daktilion (Dactylion) - Medical symbol thumb, or rather the tip of the middle finger
